If your arrows are spined correctly then yes I woud still say to adjust your nocking point and your rest a tad. By a tad I mean in incraments of about 1/32 inch. It uaually doesn't take much adjustment at all to get your broadheads and field points to shoot to the same point of impact.

The crossfire and steel force are known for being "field point accurate" broadheads. I suspect that your bow is just a tad out of tune.

This is also assuming that your broadheads spin perfectly straight on your arrows. No wobble what so ever.
